RACK FOR HOLDING WAR]? THREADS.

Original application filed August 2, 1924, Serial No. 729,666. Dividedand this application filed August 2, 1924. Serial No. 729,769.

This is a division of my co-pending ap plication, Serial No. 729766,filed August 2, 1924.

My invention relates to an improvement in racks for holding warpthreads.

The object is to provide means for holding these threads in position intwo tiers While they are being operated upon by the tying-in machine,and while the threads of the upper and lower tiers are being tiedtogether.

In the accompanying drawings Fig. 1 is a plan view;

Fig. 2 is an enlarged detail;

Fig. 8 is a transverse section on the line 83 of Fig. 1, looking in thedirection of the arrow.

Brackets 1, 2, 3 and 4.- project laterally in opposite direct-ions fromthe bed 5 of the machine. The warp threads of the spent spools arecombed over the rods 9 across the bed of the machine, and fastened andwound tight upon the inner roller 6 at the right-hand side of themachine, and a cylindrical separating-bar 7 extending inwardly from thearms 8 is then placed over the warp threads, and is forced downwardly todepress the threads slightly and held by wingnuts 13. The warp threadsto be tied are then combed over in the same way, and their ends drawnaround the outer roller 6 to give the required tension thereto, and bothrollers 6 have ordinary card covering thereon, makingthem take hold ofthe threads. The bar 7, as shown in Fig. 3, compresses the two tiers ofwarp threads, thus formed, making space for the entrance therebetween ofthe tongue of the selector of the tying-in machine (not shown).

Sleeved upon each rod 9 is a spiral spring 14 between the coils of whichthe warp threads are passed and held. The required tension is given thesprings 14; through a sleeve 15 slidably mounted on each rod, as shownin Fig. 2, and these sleeves are slidable in the frame as well as on therods, and

are held in place with the required degree of pressure against thespiral springs to cause them to hold the warp threads by any approvedmeans such as the buttons 16 held adjustable on the rods by theset-screws 17 When the tied warp threads are to be removed, it is simplynecessary to unscrew the set-screws l7 and loosen the buttons 16,whereupon the springs 14 themselves will expand, push the sleeves 15forward, and release the threads.

In this way a very quick, simple means is provided for fastening thethreads while being selected and tied.

I claim:

1. A device of the character described including a support, a rod heldthereby, a spiral spring sleeved over said rod and adapted to receivethreads drawn over the rod between its coils, a sleeve mounted on therod and adapted to be moved longitudinally thereof for adjusting thetension of the spring, and means for holding said sleeve in its adjustedposition.

2. A device of the character described in cluding a support, rods,spiral springs there on adapted to receive threads drawn over the rodsbetween their coils, a sleeve mounted on each rod and adapted to be slidto force the coils of the springs tightly against the threads, andadjustable means for looking the sleeves with the required degree ofpressure against the springs.

3. A device of the character described in cluding a support, a rod heldthereby, a spiral spring sleeved over said rod and adapted to receivethreads drawn over the rod between its coils, a sleeve mounted on therod and adapted to be moved longitudinally thereof for adjusting thetension of the spring, means for holding said sleeve in its adjustedposition, an adjustable bar for separating the rows of threads, andmeans for holding said bar in its adjusted position.

In testimony whereof I affix my signature.

HUGH P. EANES.
